Advice on edited background

Hi, just wanted to firstly thank those who gave me some advice on a couple I shot (not with a gun though :O) a few weeks ago. Basically I adjusted the backgorunds on a few in photoshop (just started learning it lol) and I wanted to get some feedback on it.

My personal feeling is that it is blurred enough, as it starts to look odd when I blur it more, but what do you think? Do you think it looks better blurred? Also just to say the edge detection tool is awesome!
